The Mon was the heraldic symbol of Japanese families and organizations. In many ways the Mon were similar to European heraldry. The Mon was used on army standards to identify the clans. Aristocratic families would pass on the Mon from generation to generation.

Traditional Japanese formal attire typically featured the Mon. However, the Mon differed from European heraldry in that commoners could use a Mon. The Mon was also not limited to identifying aristocratic families but also businesses, guilds, and even outlaw organizations. Further more the commoner could choose their own Mon, as long as it did not violate the laws of the times. This Katana features on of the most recognized Mon in Japanese history...the Mon of Tokugawa.

The sword includes a certificate of authenticity, and sword bag.

According to Japanese mythology Ryujin was the god of the seas. Similar to Chinese mythology, the ruler of the seas took the form of a dragon. His palace was under the ocean and constructed from red and white coral. Jelly fish, sea turtles and fish were his servants. The rulers of Japan would trace their lineage to Ryujin. Because of this fact, it was recorded that the Empress Jingu was able to control the tides that won the victory over the Korean navy.
